Mobile surveillance robots are supposed to cut costs. But if they keep getting into trouble and need help, they can prove to be expensive. GroundBot is unlike any other mobile robot on the market – it was originally designed to explore other planets. In other words, the nearest helping hand would have been millions of miles away. GroundBot moves through mud, sand and snow without getting stuck. The spherical design is simplicity itself. With its large circumference, GroundBot takes all kinds of terrain in its stride. And yet its appearance is friendly and unthreatening.
